能远程协助吗？不会操作
问题遇到的现象和发生背景
使用的是 《Python 编程从入门到实践》的书籍源码,显示画面异常
并且设置样式后页面加载缓慢

运行结果及报错内容
我的解答思路和尝试过的方法
没思路
我想要达到的结果
使页面应用navbar static样式
解决方案一：
你的html template里面有加上这个没有：使用在线cdn的来加载bootstrap的js和css文件，
比如在html中head中加上这句：<link href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css" rel="stylesheet">
解决方案二：
如果你的bootstrap是放在本地static目录了，你需要把static路径放到STATICFILES_DIRS里，可以参考：https://docs.djangoproject.com/en/3.1/ref/settings/#std:setting-STATICFILES_DIRS 这一节。
方式一：在线引用
前提：网络可以访问外网
在html文件的head中加入以下代码即可
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
方式二：下载到本地
django根目录下新建static/css，static/js目录
settings.py中加入以下配置
STATICFILES_DIRS = [
os.path.join(BASE_DIR, "static"),
]
将方式一种的两个链接中的文件对应下载到css、js文件夹中
前端代码中引用
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
{% load static %}
<link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}">
<script src="{% static 'js/bootstrap.min.js' %}"></script>
</head>
<body>
<a href="/logout">退出</a>
<h1>欢迎你 {{ username }}</h1>
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown"
aria-haspopup="true" aria-expanded="true">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
</body>
</html>
方式三：插件方式引用
https://pypi.org/project/django-bootstrap3/
原因
js css无法导入导致的
解决方法
重新导入js css文件即可
如有问题及时沟通
引入样式了吗？
我用#CSDN#这个app发现了有技术含量的博客，小伙伴们求同去《Django中引入bootstrap的方法》, 一起来围观吧 https://blog.csdn.net/grfstc/article/details/124581471?utm_source=app&app_version=5.3.0

一看就没有导入成功，无任何样式，你可以试一下cdn家在boostrap
